The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves separating the ventricles of the heart (the other being the posterior interventricular sulcus). They can also be known as paraconal interventricular groove or subsinosal interventricular groove respectively.
The posterior interventricular sulcus or posterior longitudinal sulcus is one of the two grooves separating the ventricles of the heart (the other being the anterior interventricular sulcus). They can be known as subsinosal interventricular groove or paraconal interventricular groove respectively.
The coronary sulcus (also called coronary groove, auriculoventricular groove, atrioventricular groove, AV groove) is a groove on the surface of the heart at the base of right auricle that separates the atria from the ventricles.
Interventricular groove may refer to: . Anterior interventricular sulcus, one of two grooves that separates the ventricles of the heart, near the left margin; Posterior interventricular sulcus, one of the two grooves that separates the ventricles of the heart, near the right margin
The crux cordis or crux of the heart (from Latin "crux" meaning "cross") is the area on the lower back side of the heart where the coronary sulcus (the groove separating the atria from the ventricles) and the posterior interventricular sulcus (the groove separating the left from the right ventricle) meet.

The PDA supplies the posterior third of the interventricular septum. The remaining anterior two-thirds is supplied by the left anterior descending artery, which is a branch of left coronary artery. It is typically a branch of the right coronary artery (70%, known as right dominance).
Interventricular sulcus may refer to: . Posterior interventricular sulcus, one of the two grooves that separates the ventricles of the heart, near the right margin; Anterior interventricular sulcus, one of two grooves that separates the ventricles of the heart, never the left margin
intertubercular sulcus, the groove between the lesser and greater tubercules of the humerus (bone of the upper arm) lacrimal sulcus (sulcus lacrimalis) malleolar sulcus; palpebral fissure, separates the upper and lower eyelids; patellar sulcus or intercondylar fossa of femur; posterior interventricular sulcus; preauricular sulcus
